Is there a way to make a table stretch across the entire page, even if it is not necessary? IE, if you go to my main page, http://www.overclockedhardware.com , you can see that the top bar stretches across the entire page... now click on "Guides".... it only goes half way... anyone know of a solution?

On the Guides page you don't have the width=100%, and on the index.html page (your front page) you don't have it specified either, but all the text (the latest news) on your page automatically stretches the table to its full width.
